Patented Apr. 9, 1918.

To all whom it may concern:

Be it known that l, EDWARD J. Von Pnrx, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certa'n new and useful Improvements in Printing Mechanism, ofwhich I declare the following to be a full, clear, and exactdescription.

This invention relates to improvements in accounting machines, and hasparticular reference to improvements in the printing mechanism thereof.

A main object of the invention is to provide a device which may beembodied in cash registers and other forms of accounting machines havingprinting mechanisms whereby, in addition to performing their usualfunctions, such machines may be made to serve satisfactorily as checkprinters or check protectors.

A number of different styles of such machines are now in general usearranged to print amounts on inserted cheeks, drafts and similar papers,one object being to enforce a record of the amounts in the recordretaining devices of the machines as an incident to the printingoperation, and another to make it more difficult to raise the amount forwhich the paper is drawn. This arrangement gives satisfactory protectionas far as the compulsory record is concerned, but does notgive a fullmeasure of protection in the way of preventing f audulent alterations ofthe amounts printed, as said amounts are usually printed in figures, andit requires the addition or alteration of but one or two figures to makesuch a fraudulent change. It apparent, of course, that increasing thenumber of ch racters wiich must be altered vill increase the difficultyof making such alterations without detection. This "an probably be bestaccomplished by printing the full words representing the differentdenominational values, instead of representing the values by figures anddecimal points.

However, the mere substitution of word printing type for the usualfigure or digit type, does not accomplish all that is necessary toproduce a satisfactory mechanism. This is because of the construction ofthe type carriers and their operating mechanism. The type carrier ingeneral use is ar-- type, the protection is, as before stated, in-' Icreased materially, but there remains to be overcome the obstacle whichhas, as far as applicant is aware, prevented prior satisfactoryapplication of word printing type carriers to machines of thedifferential type just mentioned. This obstacle is presented by the factthat the mere substitution of words for digits does not provide forsatisfactorily printing the words representing amounts between 10 and20, 2'. c. eleven, twelve and the teens thirteen to nine teen inclusivein both the dollars and cents orders. For example, such type woulc printfrom the units and tens of cents carriers the words Ten Five cents,instead of the decimal points and digits .15, while, of course, thereshould be printed Fifteen cents. This invention consists mainly in themeans by which the obstacle just mentioned is ove come.

In the aceompanyin vention is shown appli such as is fully illustraUnited States Letters latent No. 703,639, granted July 1, 1902 and No.75%.019, granted March 8, 1904;, to Thomas Carroll. However, as hasalready been stated, the invention is not limited in its application toany one particular kind of machine, but is capable of application in v-rious modifications to accounting machines in general. In fact, as willappear clearly after the construction is fully understood, the idea is gdrawings, the ine to cash register C ted and described in capable ofembodiment in structurally separate check printing or protectingdevices, such as the ordinary hand operated stamps now in general use inbanks and business houses.

It will also be aoparent after the inveu tion is clearly understood,that while the improvement is shown as applied to rotatable typecarriers, it is not limited to such an embodiment, but can be appliedwith equal facility, to. indicators .or similar devices which it may bedesirable to first differentially position and then give an additionaldegree of movement as an incident to further operation of the mechanismcomprising such devices.

\Vith the above and Fig. 3 is a chart showing the arrangement of thetype on the type carriers.

Fig. 4 is a group of details showing the type carriers in rightelevation.

Fig. 5 is a plan view of the printing mechanism. Certain of the partshave been omitted and others broken away, the object being to show tothe best advantage the parts directly involved in the invention.

Fig. 6 shows in section certain features of the control for the typecarrier operating mechanism. 4

Fig. 7 is a detail of that part of the controlling mechanism shown inFig. 6 which is designed to control the units and tens of cents typecarrier operating mechanism.

Fig. 8 shows in detail the construction of one of the lower order typecarriers, the

type being omitted from the periphery for the sake of clearness.

Fig. 9 shows how the amounts are printed on checks by the improvedmachine.

The machine of the Carroll Patent No. 754,049, to which the invention isshown applied, is one of the ones mentioned above as having ten divisiontype carriers and key controlled differential mechanism for operatingthem. In applying the invention thereto, type carriers of approximatelytwice the circumference shown therein have been used andthe width of thecarriers has also been increased. Raised word printing type are arrangedabout the periphery of the carriers and are of about the same height asthe digit type of ordinary form which they replace. The increase incircumference is to provide for additional printing spaces on the fourlower ordercarriers. In the case of the two higher order carriers, theones for incidental objects in view, the invention consists 1n certainnovel. features of construction and combinations hundreds and thousandsof dollars, no change has been made except increasing theircircumferences to make them conform in size to the lower order carriers,and, of course, the substitution of word printing type for the digittype.

The tens of cents and tens of dollars carriers have the samegeneral-arrangement of type as the thousands and hundreds of dollarscarriers,-except that they are provided with one additional printingface, while the units of cents and units of dollars type carriers, inaddition to the words substituted for the usual digits, have alternatingtherewith the words Eleven, Twelve and so on, and after each of thewords on the units carriers is the words Dollars or Cents to designatethe denominational values of words preceding in the printing line. Thearrangement of the type on all of the carriers is fully shown by thechart in Fig. 3. j The improvement consists in the mechanism whereby ona registration involving the printing of amounts from eleven to nineteeninclusive, either dollars or cents, the type carriers will first bepositioned in the usual way by the differential mechanism, and the unitsand tens carriers on which such an amount has been set up will then begiven a movement beyond that imparted by the differential mechanism.This extra movement is for convenience usually spoken of herein as ahalf step of movement because its extent is about half that of a step ofmovement imparted by the differential mech anism. The additionalmovement of the carriers will carry away from the printing line the wordon the tens carrier which was just positioned there by the difierentialmechanism and position inplace thereof type on the additional printingface above mentioned arranged to print a line of dashes.

-At the same time there will be substituted for the words set up on theunits type carriers, the adjacent words which properly represent thevalue registered. For example: If a registration involves the operationof the ten and live cents keys, the units and tens of cents typecarriers will be positioned by their differential devices to print thewords Ten Five cents. Just before the impression is taken, devicesdriven independently of the din erential mechanism, but controlledthereby, give each of the two type carriers the additional or half stepof movement. This carries the word Ten away from the printing lineand'presents in place thereof the. adjacentprinting face which, asbefore stated, is provided with type to print a line of dashes. The halfstep of movement of the cents carriers carries the words Five cents awayfrom the printing line, and substitutes therefor the adjacent wordsFifteen cents. The impression then taken will be --Fifteen cents.

Operating mechanism.

The illustrative machine is, as is well known, of the two motion type;that is, one in which entries are made by first depressing the properkeys on the ke board and then turning the operating handle. Such amachine can have any number of banks, depending upon the registeringcapacity desired. The invention has been shown as designed for a machinehaving six banks, one of which is shown in detail in Fig. 1. Theremaining banks have been omitted for the sake of simplification as theyare mere duplicates of the one shown. Each of the banks has a verticalrow of selectively depressible keys 2O ranging in value from one at thebottom to 9 at the top. The keys are held in depressed position whenoperated until near the end of an operation of the main operatingmechanism by a detent 21, (Fig. 1) and a retaining bar 22, with one endof the depressed key projecting into the path of a trip 23 carried by anoperating member 24.

The operating handle 25 (Fig. 2) has at tached thereto a pinion 26,meshing with a large intermediate gear 27 rotatably mounted on a studshaft 28 in the machine frame. The intermediate gear, in turn, drivesgears 81 and 32 attached to the shafts 33 and 34; respectively, whichextend across the ma chine. This gearing is so proportioned that twocomplete rotations of the operating handle will cause the shafts 33 and34.- to be given one complete rotation.

Dz'fierential mechanism.

Running transversely through the machine is a rock shaft 35 (Fig. 1).Attached to'this rock shaft is an arm 87 connected by a link 38 to anarm 39, fastened to the driving shaft Wh n the shaft- ?A is rotated, thearm 39 is, of course, carried. with it, thereby, through the link 38 andarm 37, rocking the shaft 35 throu h an arc of about 90 degrees, firstclockwise and then anti-clockwise, Fig. 1. During the anti-clockwisemovement, a plunger 41 carried by the operating member 2% engages a lugi2 on a plate 43 attached to a plate 36 fast on the shaft and throughthe connection so formed the operating member 2 1': is carried upwardduring the clockwise oscillation of the plate 36 until the trip 23,which is operatively connected to the plunger %1, strikes the inner endof the depressed key and causes the plunger to be disengaged from thelug d2, thereby disabling the connection between the operating member 24and the plate 36. As the plunger 4-1 is disengaged from the lug 42 it isprojected into the one of the notches L4 corresponding to the key so asto hold the operating member in its adjusted position The operatingmember 24 is formed with a rack in mesh at all times with anintermediate gear 45, and the differential adjustment of the operatingmember is transmitted through said gear and a pinion 451 to an indicatord6.

Type carrier operating mechanism.

Extending across the machine is a shaft 47 and a series of nestedsleeves 4L8 concentric to and supported by said shaft. Attached to theshaft and each of the sleeves is an arm 51 having a curved slot 52cooperating with a stud on the operating member 2st. Through thisconnection the differential movement of the operating members 2a istransmitted to the shaft at? and sleeves &8. At their right ends thisshaft and sleeves each carries a rack plate 56, Figs. 2 and 5. Teeth 5stcarried by these plates are at all times in engagement with gears 57attached to the inner ends of a shaft 59 and sleeves 60. Secured to theother ends of said shaft and sleeves are type carriers 58. The mechanismjust described is so proportioned that for each step of movementpermitted to an operating member 24 by the keys 20 the correspondingtype carrier i turned one division, thereby positioning, opposite aplaten 61, the type corresponding to the key 20 which was depressed atthe beginning of the operation.

All of the mechanism described so far is more fully shown and explainedin the Carroll patent above mentioned, and reference may be had to saidPatent No. 754,044), if more detailed information is desired.

As hereinbefore stated, the units and tens type carriers of both thedollars and cents denominations are on certain registration given a halfstep of movement by devices driven independently of, but controlled bythe differential mechanism. The means whereby this is accomplishedcomprises disks 62 attached to the sides of the type carriers, as bestshown in Fig. l. The disks for the units of cents and units of dollarsare each provided with 10 lugs 63, while the disks attached to the tensof cents and tens of dollars carriers each have but a single lug 631. Nolugs are provided for the hundreds and thousands of dollars carriersbecause they are positioned entirely by the differential mechanism, thati to say, they are never given the half step of movement which is atcertain times imparted to the four lower order carriers.

Arranged to act against the lugs 63 and 631 at the proper times areslides 64, Figs. 2 and 5, one for each of the four lower order carriers.These slides are held against lateral displacement by a slotted guide 65supported by the printer frames, and are pivoted at their rear ends toarms 66 secured to a rock shaft 67. Fastened to said rock shaft is ashort rearwardly extending arm 68, to which is pivoted one end ofaI-pitman 69 slotted to encompass the shaft .84 and carrying at itsupper end a roller 71 projecting into a cam groove 72 formed in the sideof the gear 32. It will be remembered that this gear makes acompleterotation on every operation of the machine. The configuration ofthe cam groove is such, that near the end of the operation of theshaft'34 the shaft 67 is rocked, and the slides 64 are first thrownforward and then returned to the normal positions in which they areshown'in the drawings. It Is during this forward movement, if at all,that these shoes engage the lugs 63 and 631 attached to the typecarriers to give the carriers the half step of movement above mentioned.However,

mally prevented by the forward ends of the slides being held up so thatduring their reciprocation they pass above the lugs 63 and 631, therebycausing the movements of are given the usual reciprocation their endswill engage such lugs 63 and 631 as may happen to be in their paths androtate the corresponding type carriers. The extent of the reciprocationof the slides 64 is just sufficient to rotate the carriers half thedistance that they are rotated by a step of the differential mechanism.

' The devices employed whereby the slides 64 are lowered at certainoperations will next be described. The plates 56 (Fig. 2) carrying theracks for positioning the four lower order type carriers have integraltherewith racks 81, which are constantly in engagement with gears 82(Figs. 5 and 6). The left hand one of these gears is attached to a shaft83 rotatably'mounted in the printer frames. This gear and shaft aredriven by the difierential mechanism for the lowest order or units ofcents bank. Cone ntric to and supported by the shaft 83 are threesleeves 84, each having attached to its left end one of the gears 82.These gears are driven by the differential mechanism of the tens ofcents,

' units of dollars and tens of dollars banks respectively from left toright in the order named.

Fastened to the right hand endof the shaft 83 is a gear 91 meshing witha gear 92 secured to a short shaft 93, journaled at one end in theoutsidev printer frame, and

this result is nor at the other in a boss carried by the upper end of abracket 931 (Fig. 5) attached to said frame. Rigid on the shaft 93 is asecond gear 94 (Fig. 6) meshing with a gear 95, rotating on the tens ofcents sleeve 84.

Secured'to the gear 95 so as to rotate there- 7 with is a disk 96 havingan ear 97, best shown in Fig. 7, which in the normal, or zero positionof the units of cents differential mechanismrests under a roller 98carried by the arm for the tens of cents bank, and holds said arm andits slide 64 in the raised position. The ear 97 is so shaped that if theshaft 83 is rotated even Y a single step by the units of cents difier-'ential mechanism, the slide 64 will be low 'rier is rotated morethanone step the lug 631 is carried so far that it is out of the path ofthe end of the slide.

The tens of cents sleeve 84 which, as already indicated, is the one nextto the shaft 83, carries at its right end a disk 101 (Figs. 6 and 7)having a notch 102 in its periphery. A single step adjustment of thedimes bank differential mechanism, such as occurs when the machine isoperated with the ten cent key depressed, will cause the disk 101 to berotatedone stepofrom the zero position in which it is shown, bringingthe notch 102 under the roller 98 carried by'the arm 75 for the units ofcents bank. This allows said arm and the connected slide 64 to belowered by the corresponding spring 78 so that when the slide isreciprocated its forward end will engage whichever one of the ten lugs63 carried by the units of cents type carriers happens to be in the pathof the slide 64 and rotate the carrier a half step beyond the positionto which it was previously adjusted by its differential mechanism. Inall positions of the tens of cents differential mechanism other than theone just mentioned, the units slide is held in ineffective position bythe periphery of the disk 101.

said disk under the roller 98 and allowing thearm 75 for the units ofcents bank and the slide 64 connected thereto to be drawn down toeffective position. At the same time, the differential mechanism for theunits of cents bank will position its type car ier and rotate the shaft83, gears 91 and 92, the short shaft 93, the gears 94 and 95 and thedisk 96, five steps. At the beginning of this rotation, the ear 97 onthe disk 96 is carried from under the roller 98 on the arm 75 for thedimes bank, allowing the arm and corresponding slide 6 1 to be lowered.As the one step of rotation of the tens of dimes carrier has carried thelug 681 into the path of the slide 64, when the slide for that bank isreciprocated said lug. will be engaged and the tens type carrier movedforward a half step. This will bring the space between the words Ten andTwenty, see Fig. 3, to the printing line. This space is arranged toprint a series of dashes to fill up the space which would otherwise beleft blank. During its reciprocation the slide for the units of centsbank will engage the one of the lugs 68 which was brought into effectiveposition by the five steps of rotation of the units of cents typecarrier and give the units carrier a half step of movement, carrying thewords Five cents away from the printing line and presenting in placethereofthe adjacent words Fifteen cents.

From the immediately preceding description it'is apparent that if theten cent key only is pressed, the disk 101 will be rotated the rightdistance to present its notch 102 to the roller 98 for the units ofcents bank, thereby allowing the arm 75 and slide 64 for that bank to belowered. In such a registration the units of cents type carrier will beat its normal Zero position, in which position it prints the charactersCents but these type are carried away from the printing line in theusual way by the operation of the slide 64. In order to take care of thecondition just mentioned; that is. to properly print in the unitsdivision when the ten cent key only is operated, the designation for thezero position is repeated at the next half step above on the typecarrier so that when the slide (let operates, the half step of movementimparted to the carrier will cause it to print the same character asthough the carrier remained undisturbed in its zero position. It isobvious, however. that the lug 63 at. the zero position might be omittedinstead of du alica'tin v p I:

the type for the zero position. 7

The mechanism for imparting the half step-of movement to the units andtens of dollars type-carriersis the same as the mecha for thje'units andtens of cents INS-1560111011 of produce like results. There is,therefore, no necessity for repeating the description.

In the foregoing, reference has been made to the fact that the fourlower type carriers are capable of a half step of movement independentof the differential mechanism. T he devices by which this independentmovement of the carriers is permitted are shown in Fig. 8. Each of thesefour carriers is hollow and has an internal hub 111, loosely journaledon the shaft 59 or one of the tubes 60 as the case may be. A rib 112extends between the hub and the outside shell of the carrier. Fastenedto the shaft 59 and each of the tubes 60 is a disk 113 having a slot 114through which extends a stud 115 on the rib 112. A spring 116 isfastened at one end to the stud 115, and at the other end to a stud 117on the disk 113. This construction causes the type carrier to move incorrect relation to the movement of its differential mechanism. but whena slide 64: gives one of these carriers a half step of movement, thecarrier is moved against the tension of the spring 116 until the stud115 is carried to the opposite end of the slot 114 from that at whichitis shown. lV hen the slide is drawn rearward to its normal positionthe spring returns the carrier to normal relation with its differentialdevices.

baking and impression taking devices.

An inspection of the cam groove 72 formed in the gear 32 on shaft 34;(Fig. 2) will show that after it operates the pitnian 69 to throw theslides 6% forward, it holds the pitman and slides in their operatedpeel-- tions for some little time. If the slides have been lowered andengage the lugs on the type carriers, the carriers are during this timeheld in their half step positions of adjustment against the tension oftheir springs 116. However, regardless of whether or not any of thecarriers are at the time being so hold in their half step positions, itis during this period of the operation that the position type are inkedand impression taken therefrom.

The ink for the type is supplied by a pad 121 carried by a plate 122supported at either end so as to have a slight rocking movement by stucs123 on arms carried by rotatable elements 120. The right hand one oftiese elements is journaled on the shaft 59 while the other rotatesabout the outer type wheel sleeve 60, see Fig.5". Rigid with theelements 120 are other elements 118- bearing teeth 119. For each ofthese toothed elements there is provided a pitman 125 (Figs. 2 and 5).These p'itmen have elongated openings at their forward ends surroundingtoothed elements 118 andare provided with teeth-12a meshing withtheteeth 1-19. Attheinrear ends the pit-men are slotted to straddle a shaft126 and-each times.

carries an antifriction roller 127 projecting into a cam groove 128formed in the sides of gears 129 secured to the shaft 126. The

gears 129 are in mesh with gears 130 se- :34 makes one complete rotationat each operation of the machine and the gears 129 and 130 are rotatedto the same extent. The configuration of the cam grooves 128 is suchthat at near the end of an operation of the machine the pitmen 125 arethrust forward and the teeth 124: acting against the teeth 119 cause theelements 120 to be rotated to bring the ink pad 121 over the platen 61.

, The platen 61 is raised twice during each operation. The first time itpresses the ink pad against the type carriers, after which the pad isrestored to the normal position in which it is shown in Fig. 2, and thesecond time it presses the inserted paper against the type to take theimpression from the type of the item set up thereon.

The platen 61 is adjustably mounted in a frame 135 arranged to slidevertically in a bracket 136 secured to the machine frame. At each end ofthe. frame 135 is a stud 139 projecting through a slotin the forward endof one of a pair of levers 137. The levers 137 are pivoted on a rod 138,and at their rear ends carry anti-friction rollers projecting laterallyinto cam grooves 1411 formed in the sides of gears 1412 secured to a.short shaft 143 journaled in the printer frame. These gears-are, throughthe gears 132 and 129 rotated once at each operation of the machine. Asshown the cam grooves 1&1 are arranged to operate the levers 137 twiceat eachrotation of the gears 1&2, raising the platen a correspondingnumber of As already indicated at the first operation the ink pad ispressed up against the type, and at the next the check or other recordmaterial is pressed against the face of the type. 7

Attached to the machine frame is a table 141 to receive the check orother paper on which the amount is to be printed. This table extends thewidth of the type carriers, and has an opening through which the platen61 operates. A stop 1 15, which of course may be arranged to beadjustable to different positions, serves as a guide in-placing thepaper on the table to insure positioning the paper correctly to effectthe printing at the desired point.

Operation.

In describing the mechanism, it has been necessary inc dentally toexplain the operation of the devices comprised by the imremn n 1 such aex nt; w-t r f thought that only a very brief summary of the operationis necessary here. The check or other paper which is to receive the1mpression is laid upon the table 1-14 with its mechanism controlled bythe keys and driven from the operating handle rotates the type carriers58 in the usual manner to position opposite the platen 61 the words oneach representing the different keys pressed. If the amount to beprinted does not include any of the numbers 11 to 19 inclusive in eitherthe dollars or cents orders, the impression is simply taken from thepositioned type carriers in the usual way. If, however, the amount to beprinted does involve the printing of one of such amounts, both the unitsand tens type carriers of the denominational orders involved are given ahalf step of movement in addition to the movemechanism and substitutestherefor words.

on said carrier indicating the total value represented by the two keysoperated in the units and tens banks. For example, in a fifteen centregistration the differential mechanism would operate the type carriersto position at the printing line the word Ten on the tens type carrierand the words Five cents on the units type carrier. The controllingdisks 96 and 101 would incidentally be operated by the difierentialmechanism to allow the corresponding slides 64; to be lowered so thatwhen said slides are reciprocated the lugs 631 on the tens type carriersand the-proper lug 63 on' the units carrier would be engaged, therebyrotating the two carriers a half step beyond the positions to which theywere adjusted by their differential devices. This substitutes for theword Ten, the type to print the row of dashes, and for the words Fivecents the words Fifteen cents. The type are then inked and theimpression taken while the auxiliary devices hold the carriers in theirnewly adjusted positions, and upon the withdrawal of the auxiliarydevices, the type-carriers are-returned to'their normal relations to thedifierential mechanism. 7 It is to beunderstood that while theincarriers.
